addGroupedLayersControl: Leaflet layer control with support for grouping overlays...

In bhaskarvk/leaflet.extras: Extra Functionality for 'leaflet' Package

Leaflet layer control with support for grouping overlays together.

Description

Also supports making groups exclusive (using radio inputs instead of checkbox). See the JavaScript plugin for more information https://github.com/trafficonese/leaflet-groupedlayercontrol/

Usage

addGroupedLayersControl(
  map,
  baseGroups = character(0),
  overlayGroups = character(0),
  position = c("topright", "bottomright", "bottomleft", "topleft"),
  options = groupedLayersControlOptions()
)

Arguments

map	the map to add the layers control to
baseGroups	character vector where each element is the name of a group. The user will be able to choose one base group (only) at a time. This is most commonly used for mostly-opaque tile layers.
overlayGroups	A list of named vectors where each element is the name of a group.
position	position of control: "topleft", "topright", "bottomleft", or "bottomright"
options	a list of additional options, intended to be provided by a call to groupedLayersControlOptions
